Acoustic Thermometry of Ocean Climate (ATOC) is proposed as a proof-of-concept study funded by the Strategic Environmental Research and Development Program (SERDP). The primary purpose of ATOC is to make a contribution toward meaningful climate predictions. All viable climate models show that the ocean plays a profound role in climate change. The ocean provides much of the memory which defines climate. No climate forecast, with all its consequences, will have any skill greater than that imbedded in the oceanic component. One will not get the atmosphere right unless one gets the ocean right.
